This free course, Music and its media, examines some of the main ways in which music is transmitted. It considers how the means of communicating a particular piece can change over time; and how the appearance and contents of a source can reflect the circumstances in which it is produced. The course focuses on three examples of musical media that allow us to study music of the past: manuscripts of sixteenth-century Belgium, prints of eighteenth-century London, and recordings of twentieth-century America.
